PURPOSE: To create a continuous casting roll as a component of a two-roll continuous casting installation, which, during close to final dimension casting of strips made of non-ferrous metals, may be exposed without any problem to changing temperature stresses and high roll pressures, while having a long service life. CONSTITUTION: In a casting roll which undergoes changing temperature stress and high roll pressures during the casting of strips made of non-ferrous metals for use in two-roll continuous casting installation, the sleeve of the strip is characterized in that it is made of an age-hardening copper alloy which includes 0.4 to 2 wt.% of cobalt, 0.1 to 0.5 wt.% of beryllium and a balance of copper, wherein the cobalt is partially substituted with nickel.
